CONSTRUCTION OF VERTICAL-CHAMBER OVENS.

Application filed December 17, 1920. Serial No. 431,469.

To all whom t may concern.'

Be it known that I, VVALTHER HIBY, a suby ject of the German Republic,residing at Scheveningen, Zeekant 55, the Netherlands,

have invented certain new and useful Improvements in the Construction ofVertical- Chamber Ovens, of which the Jfollowing is a specilication. f

The even heating of known vertical chamber ovens is very difficult,because the right distribution of heating gas and air for combustion israrely obtained.

In the present invention the use of hori-- zontal iues in the' heatingwalls is abandoned and the combustion as well as the oliftake of theburnt-gases is solely done in vertical iiues. Only the long sides of thevertical chambers are heated. As shown on the drawing heating gas andair for combustion are led separated one from the other to the verticalheating lines by means of hori- Zontal canals, which are situated in thelow er part of the heating wall. The regulation of heating gas and airis preferably 1done by means of dampers, arranged at the upper ends ofthe iues. In case all adjoining vertical iues would be heated directlyand the burnt-gases be taken oli" from the upper part of the oven at oneplace only and led to the heat-exchangers (recuperators), the evenheating over the total height of the chamber, would be impossible, asthe temperature inthe long heating fines cannot be the same in theirwhole length. It on the other hand alternate burnt-gas tlues are builtbetween the heating flues proper, then an exchange of heat occurs. Theburnt-gas takes heat from the hottest parts of the adjoining directlyheated lines and carries it to lesserheated parts of the chamber wallsand an keven heating is assured. a

Figure 1 is a vertical section of the ovens passing thru a heating wallon line 1 1 ofV Fig. 2.

Fig. 2 is a transverse section thru heating walls and oven chambers online 2 2 of Fig. l. Y

Fig. 3 is a horizontal section taken respectively on lines 3 3, 4 4, 5 5and 6 6 of 50 Fig. l.

The invention is shown on the accompanying drawing in Figures l, Zand.3, a are the vertical coking chambers with the interposed heating wallsb. In the walls b are situated the directly heated flues c, whichalternate with the double lues d for the 01T- talre of the burnt gases.The heating gas is led to the single lues c from pipe e by means of abranch pipe f and the horizontal canal g, from which it dischargesthrough openings L into each iiue c. The air for combustion enters theheat-exchangers (recuperators) through openings c' into chambers 7c,passes through the same in upward direction in counter-current to theoheat, is collected in the canal Z, goes sideways to the heating wall,discharges through openings m and meets in -two streams the heating gas,streaming from openings 7L.

The lues c are, as described, heated directly, while the burnt-gas goesdownward through the double lues d, to be collected in the canals a; itgoes sideways to the heatexchangers, passes downward in the latter indouble flues 0 in counter-current to the rising air and is led throughopening p, regulated by a sliding damper r, to the chimney lines g rlfheeven heating of all iues c is effected by adjusting thefgas pressure inthe pipe e and canaly g and by regulating the upper outlet openings offlues c by means of dampers s. The burnt-gas is evenly distributed tothe flues 0 fot the heat-exchanger by means of regulating-dampers t.

Having now described my invention what I claim as new and desire tosecure by Letters Patent is:
